the-object of the invention is to devise a vform or construction of crib which may be built by unskilled labor at a minimum expense and have a maximum stren th for a minimum is especially-adaptable for concrete sup'erstructures, which-may bemad'e in a sheltered spot. and then readilyl towed into place and' sunk, using the cheapest or any suitable form offilling with the least` expenditure of time, thereby avoiding exposure to the action of the waves, and such va crib as may be advantageouslypused as a scow or pontoon for carrying the iilling ma? terial forconstructional work, which will maintain its shape andrigidity when filled,

My invention consists in .thearrangement of face-timbers, cross face-timbers, longitudinal timbers, cross-ties, interior sheeting, floor, and deck,o all bound together in trusslike form, as hereinafter more particularly igure 1 is a perspective viewfofafcorner portion of a cribconstructed in accordance with my invention, the deck being for the most part removedand the crib .being'other-` Wisebroken away and in section, and the-ce- Y ment superstructure being also shown in B the longitudinaltimbers located,interme.

roof:

the flooring in place when the space isgnext 105' be noticed that the bolts, as indicated by such lines, extend through from the uppermost timber down to the bottom of the lowermost timber.

L is the vertical sheeting, which is preferably doubled and breaking joint, as indicated, and which extends around inside of the facetimbers on all sides from the top of the uppermost longitudinal timber to the flooring,'be ing, if necessary, at the fiooring and at the top suitably calked, so as to form a water-tight Joint.

M is the deck planking, which extends crosswise, as indicated, and is provided with longitudinal cleats N, on which is molded by any suitable means a concrete superstructure O of any preferred form, such as shown in the drawings. The outer face of' this concrete superstructure is provided with the longitudinal waling-timbers. The concrete superstructure, it will be noticed, at the bottom fills the sp ace between the cleats, thereby securely holding such structure in position and against lateral displacement by the impact of the waves.

The deck-planking M, hereinbefore referred to, fits closely upon the top of the vertical sheeting.

The longitudinal timbers of the portion of the crib, as shown in Fig. 1, which extends at right angles to the main portion necessarily form the cross-timbers at the corner where they cross the longitudinal timbers of the main portion, as will be readily understood, and the longitudinal timbers of the main portion form the cross-timbers of the right-angular-extending portion hereinbefore referred to. Consequently by this construction a very strong corner is providedfor the crib. This is only so of course where a corner is made in the cribwork.

b' One crib is connected to the end of the other by means of the longitudinal connecting-timbers P, which are bolted at the inside to the sheeting and the face-timbers by the bolts Q. The ends of the longitudinal connecting-timbers project beyond the end of the crib, so as to extend into a corresponding position in the abutting crib. As there may be several of these connecting-timbers,one above the other on each side, it will be seen that the method of ,connecting the cribs is very secure and effectual.

Such a crib as I describe can be built with less timber and less iron than others ofwhicl I am aware. The sheeting may be tongued and grooved, if necessary, so as to insure against leakage.

The crib may be filled with stone, gravel, or furnace-slag when exposed to the action of a heavy sea, but in quieter water sand, clay, or heavy mud can be used when the cribs are backed up on one side for use as wharves.

When the sheeting'is calked, the crib may be partially filled with ballast before being towed into position where it is placed, thus saving valuable time in sinking it. It may be also used as a scow or pontoon.

As all the bolts are through-bolts, the crib will not break apart as where the cribs are built with drift-bolts.

It can also be used as a caisson, the water being pumped out and the concrete laced in position in a solid mass instead of locks of concrete having to be molded for use below water-level. It is specially adapted to be used below water-level, and when so placed will last indefinitely.

The crib may also be built with any desired slope or batter when used in a seaway, and when exposed to a very heavy sea the face can be covered with pl anking down to the bottom of the trough of the sea, so that there will be nothing to obstruct the action of the waves, which will expend their force gradually by running up the slope. It is also to be noted the great strength of the corners hereinbefore referred to.

In the construction of the crib all the timbers may be marked or bored from templets, thus avoiding much time and labor.

It will be noticed that each of the sides, ends, rows of ties and longitudnals are trusses, and as the floor is supported by these trusses it cannot sag under its load of ballast. In fact, to put it shortly, my crib is made of a truss-frame which carries all strains including flotation and load strains.

What I claim as my invention is 1.' In crib construction, a crib comprising bottom, longitudinal face-timbers and crosstimbers, a fiooring supported on the same, the intermediate and upper face longitudinal and cross timbers resting at the ends one on the other, so as to form intervening spaces, the interior sheeting secured to the interior of the face cross and longitudinal timbers and forming a closed water-tight receptacle as and for the purpose specified.
